Identify conversion formula: Identify the conversion formula from degrees to radians. The formula to convert degrees to radians is radians=degrees×(180°π).
Convert 540 degrees: Convert 540 degrees into radians using the formula. By substituting 540 degrees into the formula, we get 540∘×(π/180∘)=3×π radians.
Perform calculation: Perform the calculation to find the exact radian measure. 540°×(π/180°)=3×π=3π radians.
Choose correct option: Choose the correct option of radians for 540°. The correct option is 3π radians, which is equivalent to 540°.
